Understanding the Costs

Blended Charging Explained

Most EV owners charge at home overnight at a cheap rate, and top up at more expensive public chargers. Our  calculator uses a 'blended' rate based on your home/public charging mix to give a realistic running cost.

The EV 'Breakeven' Point

EVs often cost more to buy but are cheaper to run. The 'breakeven' point is the number of years it takes for your fuel savings to cover the initial price difference. Our calculation helps you see when your investment pays off.

For official EV charging guidance, visit GOV.UK EV charging guide. You may also want to explore our Solar Panel Calculator to see how much you could save by generating your own electricity for home charging.
